By reading several post about "adding new activity", I have understood it is not possible to add a new activity that is not already defined in the Garmin activity list. This is not good for me, but it has been understood.
My usual activity is tennis, but I can not add and select it in my Garmin instant.
However it is not clear to me another point: in the menu, in the "activity and app" it is possible to define a new activity. It is not clear to me how I can use the activities defined in this section, both the new defined by me and the ones already defined by Garmin, such as "track me", "navigator", "area calculation", etc.
How can I select those activities?
Thank you in advance
